CausesValidation=false不清空数据

本文关键字：清空 数据 false CausesValidation | 更新日期: 2023-09-27 18:05:32

我通常在我的web表单中使用CausesValidation=false，它工作，但它不工作在下面的表单。如果我输入一些数据，然后点击RESET按钮，所有必填字段(*)将消失;但是，它不会清除文本框或单选按钮中的信息。我试着添加Javascript OnClientClick="this.form.reset();return false;"，仍然没有工作。我检查了一遍又一遍我的剧本，我在网上搜索，但我找不到一个解决方案。可以有两对<section></section>标签在同一个<面板>造成了问题?只是好奇。我注意到我之前的表单只有一对<section>在每个表单中标记;这是我第一次有两个部分。

CausesValidation=false不清空数据

在纠正标记并为resetBTN删除OnClientClick之后，它似乎具有所需的行为(当按下'reset'时形式被清除):
